Effects of sugarcane bagasse ash as partial replacement of cement in the compressive strength and light transmissibility of Litracon blocks

Living up to a culture of sustainability and efficiency, the Light Transmitting Concrete or Litracon came to its prominence recently. Aside from that, the increase in the production of cement for building structures to facilitate various social dynamics has contributed to the world’s exponentially increasing carbon emissions. Thereby, this study acts upon both phenomena by partially replacing the cement in the concrete mix for producing Litracon blocks using an agricultural waste material called Sugarcane Bagasse Ash or SCBA while aiming to improve their structural performance. The study used five (5) mix designs of 2.5%, 5%, 7.5%, and 10% replacements, and a controlled mix with no replacement. Three (3) cubic samples of 150 mm side dimension for each mix were subjected to the light transmissibility test before the compressive strength test. Results showed that the illumination values in lux of 103 to 120 were at par with the Philippine illumination guidelines for interior rooms, from 100 to 150. Moreover, the highest recorded compressive strength result with SCBA percentage replacement was the 5% design mix at 28.81 MPa, and the 2.5% design mix had the lowest recorded compressive strength of 23.51 MPa. The results further showed that even with no significant relationship between the percentage replacements and compressive strength values from the two-tailed T-test, no significant difference between such strength values was found using the One-way ANOVA test. Thus, this supports the claim that SCBA can partially replace the cement used for the concrete mix of Litracon blocks.

Investigating The Combined Effects of Replacing Cement with Sugarcane Bagasse Ash and Coarse Aggregate with Ceramic Tile Waste in Concrete Production

In pursuit of sustainable and innovative construction practices, this study investigates the combined effects of sugarcane bagasse ash (SCBA) and ceramic tile waste (CTW) as subsititue to aggregates on concrete properties, aiming to optimize their usage as eco-friendly alternatives. However, SCBA is a waste product of sugar industry. As a result of increasing recognition and understanding of sustainability and recycling in academia and industry over the past several decades, sustainability and recycling have become increasingly significant. It is also important to note that recycling construction waste and debris is one of the opportunities available for reducing construction waste. To optimize the amount of cement replaced by SCBA, the cement was partially replaced by SCBA and the ceramic waste was replaced at different dosages of 10%, 20%, and 30% by weight of coarse aggregates. Different properties such as workability and compressive strength have been evaluated during 7 and 28 days following replacement by SCBA and CTW. The results further revealed that the workability decreased with the inclusion of SCBA and CTW due to water absorption by the CTW and SCBA particles. However, the compressive strength of concrete mix was relatively higher at 10% replacement of cement by SCBA and 10% replacement of CTW, after which it decreased beyond 10% replacement. The maximum compressive strength was observed as 29.31 MPa with 10% SCBA and 10% CTW at the age of 28 days which is around 9.7% higher than the control mix concrete. It was deduced from the results of this study that 10% SCBA and 10% CTW replacement by the cement and coarse aggregates respectively, could be considered asoptimum replacement.

An investigation on the effectiveness of quarry dust and sugarcane bagasse ash in Na-based alkali-activated binder

The use of river sand as fine aggregates has been banned in several countries to protect river bed. Hence, a significant shortage is currently faced for fine aggregates. Although earlier studies have been reported for alternative fine aggregates, these studies were mostly carried out only for cement concrete. Studies on using alternative fine aggregates in alkali activated concrete with emerging precursors like sugarcane bagasse ash are minimal. Therefore, the current study assesses the performance of sugarcane bagasse ash-based alkali-activated binder along with quarry dust as alternative fine aggregate. NaOH and Na2SiO3 were used as activator. Sugarcane bagasse ash-based alkali-activated specimens were subjected to both ambient and heat curing to evaluate the curing effect. Five alkali-activated concrete mixtures were cast with 0, 10, 20, 30, 40 and 50% of quarry dust. Moreover, the effect of sugarcane bagasse ash as a precursor (10, 20, and 30% SCBA as a replacement of the GGBS) was evaluated for quarry dust aggregates used alkali-activated binder. From the study, 20% of quarry dust is found to be the optimum replacement level for river sand. The compressive strength of the 30% bagasse ash-20% quarry dust based heat cured alkali activated specimensis decreased 35.1% compared to the control specimens. Ambient-cured sugarcane bagasse ash-quarry dust based specimens exhibited better strength than the heat-cured specimens. Even though, the compressive strength of the bagasse ash-slag based alkali-activated specimens is lesser than control specimens, the obtained strength is well above the minimum required strength for several structural applications.

Effect of sugarcane bagasse ash and plantain leaf ash on geotechnical properties of clay soil from Efab Estate, Awka, Anambra State

This study investigated the feasibility of using agricultural wastes: sugarcane bagasse ash and plantain leaves ash for clay soil stabilization. The sample was mixed using five trial mixes: 0%BA:10%PLA, 3%BA:7%PLA, 5%BA:5%PLA, 7%BA :3%PLA, 10%BA:0%PLA and a control mix. Characterization of these ashes was done using the X-ray fluorescence testing method. Specific gravity, sieve analysis, Atterberg limits, compaction and California bearing ratio tests were also assessed. The clay soil was described as A-7-6 (AASHTO). After X-ray characterization, BA and PLA possessed 61.97% and 28.27% pozzolanic content respectively. From the liquid limit results, on addition of 3%BA :7%PLA, a significant decrease in values of 47.0%, 32.0% and 15.0% to 36.0%, 26.0% and 10.0% for LL, PL and PI was documented. Also, the addition of plantain leaves alone significantly decreases atterberg limit values. For compaction, 3%BA and 7%PLA recorded the least MDD value of 18.44kN/ m3 and peak value of 19.42kN/m3 at 0%BA: 10%PLA. 10%PLA and 10%BA recorded CBR soaked values of 57.8% and 62.1% whilst 7%BA:3%PLA yielded best results of 51.3% CBR soaked values. These findings reveal significant improvements in strength and index properties of the clay soil. In conclusion, bagasse ash and plantain leaves ash produce an eco-friendly stabilizer that can be utilized as subbase material in the stabilization of clay soils

Effect of sugarcane bagasse ash on compressive strength and water absorption of foam concrete using sea sand and seawater

The rapid development of infrastructure has led to a shortage of construction materials. Therefore, the utilization of waste or potential materials is gaining attention. This study aims to investigate the effect of partially replacing Portland cement with sugarcane bagasse ash (SCBA) in Phu Yen province and sea sand-seawater (SSSW) on the properties of foam concrete. Portland cement was replaced with SCBA at 0, 5, 10, and 15% by mass of the binder. The results showed that the compressive strength of foam concrete was reduced at 7 days due to the SCBA replacement. However, the inclusion of 5% and 10% SCBA increased the compressive strength and reduced the water absorption of foam concrete compared to the reference concrete at 91 days. Moreover, the combination of SCBA and SSSW significantly contributed to the enhancement of compressive strength and reduction of water absorption of foam concrete at 91 days, especially when SCBA replacement was less than 10%. In general, the use of SCBA and SSSW is feasible in the production of foam concrete, considering the increasing scarcity of construction materials and the goal of reducing CO2 emissions.

Effect of SCBA and GGBFS on mechanical properties and microstructure of concrete under elevated temperature

Concrete is a naturally occurring mixture of fine and coarse material bonded together by water-based cement. The use of waste material as cement replacement is regarded as one of the most well-linked improvements in the construction sector. Sugarcane bagasse ash (SCBA) which is an agricultural waste, whereas ground granulated blast furnace slag (GGBFS) is an industrial by-product that is used as a cement substitute. Concrete is vulnerable to damage when exposed to temperatures that are substantially greater than room temperature. In this investigation, M25 grade of concrete with replacement of cement by SCBA and GGBFS at 15%, 20%, 25% and 30% with regulated curing was employed. This investigation examined strength in compression, mass loss ratio, ultrasonic pulse velocity (UPV), physical behavior, and microstructure in terms of scanning electron microscope (SEM) under elevated temperature. The specimen is held at a temperature of 200 °C, 400 °C, 600 °C, & 800 °C for two hours following a 28 days curing period. It was reported that strength in compression improves up to 400 °C before it starts to decline. At higher temperatures, color change and cracking were seen in addition to a fall in UPV value and mass loss.

Properties of Cement Pastes Replaced Partially by Sugarcane Bagasse Ash

In the present study, experimental program is carried out to study the effect of sugarcane bagasse ash (SCBA) on the various properties of Ordinary Portland Cement (OPC). To do so, various paste specimens were cast with OPC replaced by 10%, and 20% SCBA by weight of cement. The studied factors include compressive strength, apparent porosity, ultrasonic pulse velocity, and sorptivity. To quantify the SCBA potential, the results of OPC replaced SCBA specimens were compared than that of the OPC specimen. From the results, at the higher percentage replacement of SCBA, compressive strength was found to reduce significantly. Moreover, results of an ultrasonic pulse velocity tests revealed that the quality of paste specimen reduces with the increase in percentage replacement of SCBA,

Effects of sugarcane bagasse ash and nano eggshell powder on high-strength concrete properties

There are many problems due to the cement industry around the world besides the air pollution by greenhouse gas emissions. The problem arises when a dense quantity of CO2 is emitted through the conversion of calcium carbonate lime (CaCO3) into calcium oxide lime (CaO), the main ingredient in cement. This transformation is made in an oven-dry by burning fossil fuels, in a process that releases more carbon dioxide. In this study, sugarcane bagasse ash (SCBA) and nano eggshell powder (NEP) are considered cementitious materials and were added to the cement at different percentages to reduce the cement contents in the concrete industry. Sixteen high-strength concrete (HSC) mixtures experimented with in this investigation contain SCBA and NEP other than the control mix. The SCBA and NEP were added to cement content by 5 %, 10 %, 15 %, and 20 % for SCBA, and 2.5 %, 5 %, and 7.5 % for NEP. This study evaluates the fresh and hardened properties of HSC. Also, EDX and SEM analyses were conducted on the SCBA, NEP, and HSC concrete to analyze the microstructure. The experimental results exhibited that the setting time of HSC is delayed by increasing the SCBA ratio by 25 % of the control mix. Adding NEP accelerates the HSC setting time compared with the control mix. The best mixture result includes 5 % NEP with 15 % SCBA, which exhibited a dense form, no pores, and no cracks, as analyzed in the microstructure.

Growth and physiology of two sunflower cultivars fertilized with sugarcane bagasse ash

One way to reduce mineral fertilizers is to use alternative fertilizers instead, such as the byproducts from the food industry. In the present study we evaluated the effects of sugarcane bagasse ash on the physiology, growth, and development of sunflowers (Helianthus annuus L.). We conducted an experiment in a greenhouse using a completely randomized design with two sunflower cultivars (Multissol and Catissol), five sugarcane bagasse ash doses (0.0, 3.125, 4.687, 6.25, and 7.812 mg ha-1), and 5 replicates. At 85 days after planting we determined the plant height; leaf number; stem diameter; internal and external diameter of the flower chapter; leaf area index; shoot dry weight; net assimilation rate; dry mass production rate; relative and absolute growth rate; extravasation of electrolytes; relative water content; photosynthetic pigments (chlorophyll a, b, carotenoids, and the chlorophyll a/b ratio); and soluble carbohydrates, proteins, and proline. The height, number of leaves, and shoot dry mass increased due to the availability of nutrients contained in the ash. The incorporation of ash into the soil increased the photosynthetic activity (chlorophyll a and b) of both sunflower cultivars. The diameter of the stem, leaf area index, and relative growth rate of both sunflower cultivars increased with increasing ash dose. Therefore, the ash can be used as an alternative fertilizer, complementing or replacing mineral fertilizers.

Variability in the compressive strength of non-conventional bricks containing agro and industrial waste

The present study is mainly focused to address the uncertainty underlying compressive strength of non-conventional bricks along with clay brick using agro and industrial wastes such as sugarcane bagasse ash and waste marble dust; but utilization of both the materials in a single brick is very scanty. Keeping view on this, an attempt was made in the study to understand the effects of sugarcane bagasse ash along with the waste marble dust as the partially replaced material for the production of bricks. However, the compressive strength of brick is the main critical parameter further an extensive study was also done through the probability study. To undertake the current proposal economically; a semi - automatic fly ash brick manufacturing machine was fabricated locally with hydraulically operating system. To prepare the nonconventional brick, three different types of combinations as Type I, II and III were considered and based on the minimum values of the suggested Indian codal provision for compressive strength, with the composition of fly ash brick as fly ash-25 %, sugarcane bagasse ash (SBA)-20 %, sand-30 %, cement-5%, waste marble dust-20 % and for clay bricks as clay of 65 % with SBA 35 % are finalized for further statistical analysis. The study concluded that, the variability of the characteristics compressive strength of both fly ash and clay brick can be described with normal distribution at 5% significance level. The regression analysis for the compressive strength of bricks concluded with a linear relationship with R2 = 0.996 and 0.992 respectively for both the bricks type considered. Further the embedded irregularities in the data of above-mentioned bricks types confirm the adoption of statistical techniques. Owing to the satisfactory results of characteristic compressive strength, the utilization of sustainable fly ash bricks in the present study can be encouraged subjected to the ample availability of raw materials in a locality.

Effect of Sugarcane Bagasse Ash as Partial Cement Replacement on the Compressive Strength of Concrete

The disposal of solid waste in open environment is a serious alarming concern that needs immediate attention from the researchers. The hazardous solid agro-industrial wastes which include: wheat straw ash, rice husk ash, corn cob ash and sugarcane bagasse ash (SCBA), having pozzolanic properties, have a versatile use in concrete. The solid pozzolana enhances the various concrete properties by the reaction of silicates with calcium hydroxide in the presence of water, which in result generate a saturated zone of calcium silicate hydrate (CSH) gel. This C-S-H gel reduces the amount of calcium hydroxide C(OH)2 during the hydration process of cement. Very limited research works have been done on concrete by partially replacing cement with SCBA. This research work was focused on evaluating the properties of concrete by partially replacing cement with SCBA at 0, 5, 10, and 15 percentages. Compressive strength, Strength activity index, and water absorption of all mixes were examined. And it was observed that all SCBA mixes showed an increase in compressive strength and at 10% replacement the strength activity index was at a peak of 115.67%, but all the SCBA mixes showed a strength activity index greater than 75% which satisfied the standard specification. The water absorption test for all SCBA mixes showed a slight increase in water absorption.

Synergic Effect of Sugarcane Bagasse Ash Based Cement on High Performance Concrete Properties

High performance concrete (HPC) is produced in this study by utilizing the agriculture industry by-product. The usage of by-product helps to condense the disposal issues, ecological degradation and also makes the production of concrete economical. The raw sugarcane bagasse ash from sugarcane industry is processed to ensure the suitability with the properties of cement to be used in HPC. Sugarcane bagasse ash (SCBA) is used as binder in HPC as an alternative of ordinary Portland cement. The properties of the SCBA have been studied. Investigation were carried out experimentally on M 60 grade of high performance concrete blended with SCBA to assess the workability, strength and durability properties at different ages of curing. Three SCBA blended HPC specimens were tested for each trial and test. Test results indicate improved performance in strength and durability properties up to 15% substitution level of SCBA with ordinary Portland cement.

Effects of adding sugarcane bagasse ash on the properties and durability of concrete

Ashes from biomass burning, such as from sugarcane bagasse, have great potential as supplementary cementitious materials. The sugarcane bagasse ash (SCBA) possesses high pozzolanicity. However, limited studies have investigated the influence of SCBA on the durability of concrete. A knowledge gap exists regarding the influence of these ashes on the lifetime of reinforced concrete in terms of chloride migration and carbonation. Moreover, additional studies on the effects of SCBA on the alkali–silica reaction (ASR) are essential because this ash generally has a high alkali content. In this study, the effects of adding 5%, 10%, and 15% SCBA on the properties and durability (chloride migration, carbonation, and alkali-aggregate reaction) of concrete were investigated. Furthermore, the SCBA pozzolanicity was evaluated and lifetime estimations in terms of chloride ingress and carbonation were performed. The studied ash demonstrated high pozzolanic activity, which reduced the porosity and water absorption by capillarity and increased the mechanical strength of the concrete. However, because the alkaline reserve was reduced, the concrete with SCBA exhibited a higher carbonation rate (up to 69%) and a shorter lifetime regarding carbonation. Nevertheless, all concrete specimens had a lifetime of more than 50 years in an industrial environment, except for that with 15% SCBA. Adding SCBA also reduced the chloride diffusion coefficients, increasing the lifetime by up to 97.3%. SCBA addition of up to 5% mitigated the ASR owing to the pozzolanic reaction and additional C-S-H formation.

Effect of Sugarcane Bagasse Ash and Lime Stone Fines on the Mechanical Properties of Concrete

Cement production releases huge amounts of carbon dioxide having a significant impact on the environment while also having huge energy consumption demands. In addition, the disposal and recovery of natural concrete components can lead to environmental degradation. The use of waste in concrete not only reduces cement production, but it also reduces energy consumption. The aim of this study is to evaluate the properties of fresh and hardened concrete by partially replacing cement with sugarcane bagasse ash (SCBA) and limestone fines (LSF). In this investigation work the cement was replaced with SCBA ash and LSF by 0% (0% SCBA+ 0% LSF), 5% (2.5% SCBA+ 2.5% LSF), 10% (5% SCBA+ 5% LSF), 15% (7.5% SCBA+ 7.5% LSF) and 20% (10% SCBA+ 10% LSF) by weight of cement. In this regard, a total of 60 samples of concrete specimens were made with mix proportion of 1:1.5:3 with 0.56 water-cement ratio. Cube specimens were tested for compressive strength and cylindrical specimens were used for determining splitting tensile strength at 7 and 28 days respectively. The optimum result displayed that the crushing strength and split tensile strength increased by 10.33% and 10.10% while using 5% SCBA+ 5% LSF as a substitute for cement in concrete after the 28th day. The slump value of concrete declined as the content of SCBA and LSF increased.

The Effect of Sugarcane Bagasse Ash on the Properties of Portland Limestone Cement

This paper tries to investigate sugarcane bagasse ash (SCBA) as a cement replacement material and its effect on the water consistency, setting times, soundness, specific gravity, water absorption and mortar compressive strength of SCBA-Portland limestone cement (PLC) blend at cement replacement from 0 -15 wt.% at interval of 2.5 wt.%. Calcination of sugarcane bagasse was conducted and the optimum condition was obtained ash at 650°C at 90 mins with a higher Si + Al + Fe content from nine compositional analysis of ashes obtained via X-ray fluorescence spectrometer and then employed as cement replacement material for this research work. The consistency and setting times of the blended cement samples were carried on paste using Vicat apparatus while the soundness, specific gravity and compressive strength using Le Chatelier apparatus, density bottle and strength testing machine respectively according to ASTM standards respectively. Results showed an increase in the water consistency and setting times of SCBA cement pastes as SCBA content was increased from 2.5 – 15wt.% which was attributed to unburnt carbon present in the ash due to its high LOI. The elongated setting times could also due to clinker diminution by cement replacement with SCBA and high-water demand. The SCBA cement blends produced accelerated setting time results compared to PLC owing to lime present in SCBA which enhances early hydration. The specific gravity diminished while the volume expansion of the SCBA cement pastes experienced an increase as SCBA was increased due to lower density of SCBA compared to PLC and increased lime content due to increased SCBA content respectively. An increase in the mortar compressive strengths of SCBA cement blends was experienced as the curing days progressed from 3 to 60 days. PLC blended with SCBA produced an enhanced early strength due to the presence of lime which tends to accelerate the rate of formation of hydration assembly. Whereas, at a high cement replacement of 12.5 wt.% SCBA produced exceptional mortar compressive strength especially at 60 days despite clinker diminution indicating pozzolanic activity due to SCBA inclusion. The optimal cement replacement with SCBA was observed at 5 wt.% in comparison with control especially at 28 days and did not adversely affect its strength owing to pozzolanic activity.

Synergetic Effect of Sugarcane Bagasse Ash with Low Modulus of Fiber Reinforced Concrete

This research work has experimentally investigated on the effects of low modulus fibers (PP) used in concrete for the various percentages like 0. 0.5% and 1.0% (by volume fraction) along with different percentage of sugar cane bagasse ash from 0 to 15% replaced in Portland cement (by weight of binding material) for different mixes and tested for the various properties of high-performance concrete (HPC). This experimental test results indicated that the usage of SCBA is restricted up to 10% with 0.5% of PP (Polypropylene) along with 1.5% of superplasticizers produces the higher flexural strength was increased up to 78.30% and compressive strength of concrete was increased up to 25.80% when compared to control (plain) concrete at 28 days. Finally, the usage of low modulus fibre reinforced concrete to act as a corrosion inhibitor agent during the chloride attack than compared to high modulus fibers and reduce the plastic shrinkage due to excellent flexibility in concrete and also increases the life span.

MANUFACTURE OF SOIL-CEMENT BRICKS WITH THE ADDITION OF SUGARCANE BAGASSE ASH

ABSTRACT The objective of this study is to evaluate the effect of sugarcane bagasse ash on the compressive strength and water absorption index of soil-cement bricks. The ash was sieved without chemical and/or physical treatment to reflect the use of this material in real manufacturing processes. The addition of natural ash decreased the quality of the bricks, reducing the compressive strength and increasing the water absorption index.
